I too had breast ca then developed MAC. I was put on the 3 Antibiotics in 2009. Did not receive any follow up or advice at MD Anderson where I was treated and decided myself to go off the meds after 9 months. Now in 2018 , my cough is back and the fatigue is extreme . I have basically had no treatment but for the icassiinalt Zithromax my GP was providing . I am basically a. Invalid now not really going out. I need some treatment and MD Andrrson won’t really treat. I am so glad to get to this site and all of you because I did not know anyone who had the disease except a guy who had part of his lung cut out. Where should I go for treatment ? Which is the best clinic and the best doctors. I was really ready to give up until I heard all of your voices! Thank you did much ! I had just felt so alone in this and the doctors I saw just didn’t want to get involved in this disease.
